Day For Knight
In Kevin vs. the Volcano, the Porters watch in horror as a volcano in the distance erupts.
One day a volcano in the distance erupts in the Land, sending lava in the direction of the Porters tree house. Tom and Christa attempt to divert the lava flow by moving a huge boulder into its path through a narrow valley, but the lava seems unstoppable.
When Kevin falls into a hole while battling Scarface, he finds what could be the answer. In an ancient subterranean cave, he finds forgotten Sleestak technology: a glowing crystal structure. Tom speculates that it is an energy generator, and perhaps if the Sleestak were sufficiently advanced once, perhaps they placed the device to keep them from erupting.
In the end, the device is able to reverse the lava flow, and undo the eruption entirely.
